Technical Field

[0002] Corrosion-resistant high-frequency circuit boards are special circuit boards with higher electromagnetic frequencies. Generally speaking, high frequency can be defined as frequencies above 1GHz. They have very high requirements for various physical properties, precision, and technical parameters, and are often used in automotive anti-collision systems, satellite systems, radio systems, and other fields.

[0003] For example, a corrosion-resistant, low-loss, high-frequency mixed-voltage circuit board with publication number CN217694079U protects the corners and middle of the circuit board by setting structures such as airbags, pull rods, springs, and damping blocks, achieving multiple buffers and improving the durability of the circuit board. However, the circuit board will face corrosion and wear during use, and only improving the impact resistance cannot meet the needs of the circuit board in a complex environment. For this reason, a corrosion-resistant, low-loss, high-frequency mixed-voltage circuit board is proposed for improvement. Utility Model Content
